Why did most people support pacifism?

Most people supported pacifism due to the devastating consequences of war, particularly after experiencing the horrors of World War I and World War II. The loss of life, destruction, and lasting trauma led many to advocate for peaceful resolution of conflicts and to promote diplomacy over violence. Additionally, the rise of humanitarian and ethical philosophies emphasized the value of human life and the belief that peaceful coexistence was preferable to military aggression. This sentiment often aligned with broader movements for social justice and civil rights, which sought to address systemic issues without resorting to violence.
